Resumen

La industria textil, una de las de mayor crecimiento, enfrenta grandes desafíos relacionados con la persistencia del color de los productos y el tratamiento de aguas residuales generadas durante su proceso. La decoloración de los colorantes utilizados, como el "Taicron Red", es un problema importante, ya que estos colorantes son químicamente estables y difíciles de eliminar. Por ello, es fundamental desarrollar métodos eficaces y sostenibles para su tratamiento. El objetivo de este estudio fue evaluar la eficiencia de un sistema de tratamiento para la remoción de colorante textil "Taicron Red" en soluciones modelo, utilizando procesos sostenibles alimentados por energía solar. Para ello, se diseñó y construyó una celda electrolítica alimentada por panel solar y un fotorreactor cuya bomba también es impulsada por energía solar. El tratamiento consistió en un proceso de electrocoagulación con ánodos de aluminio, aplicando una diferencia de potencial de 12 voltios durante 40 min, lo que redujo la Demanda Química de Oxígeno (DQO) de la solución de 5216,7 ppm a un valor inicial que permitió una segunda electrocoagulación. Posteriormente, la solución fue tratada en el fotorreactor durante 180 minutos utilizando 100 mg de Fe (II), 12 ml/L de H₂O₂, pH = 3 y TiO₂ a 100 ppm, logrando una remoción del 60% de la DQO (removiendo 3129,2 ppm) y del 90,68% del color. En un segundo tratamiento, incrementando la concentración de TiO₂ a 1000 ppm, se alcanzó una remoción del 84% de la DQO (removiendo 4381,4 ppm) y una remoción del color del 99,38%. Los resultados demostraron que el sistema propuesto es altamente eficiente para la remoción de colorante textil y DQO, alcanzando altos porcentajes de remoción en ambos casos, y que el uso de energía solar en conjunto con los procesos de electrocoagulación y fotocatálisis resulta ser una alternativa viable y sostenible para tratar aguas residuales en la industria textil.
